This invention. Arelates to new and useful improven'ients in polishing tools and aims to provide a tool that is primarily adapted'for use in the poli 'hing of watch jewel settings.

ln carrying out the present invention there is provided a tool consisting generally of a handle and a polishing head, said head being so associatedpwith the handle as to be nor nially projected therefron'i and* wherein means is provided so that when the head is arranged Within a. jewel setting, aspressure upon the handle will cause the rotation of the iead in one direction, whereas a releasing of the pressure willrcause the outward move# ment of thehandle and a. simultaneous reverse rotation of the head.

The accomplishment of the foregoing ep-` eration of this tool is provided through the medium of extremely simplified construction, enabling the too-l to be manufactured at nominal cost, the structural elements of the tool being so re-lated as to permit the sam-e to be disassembled and at the same time toreduce to a minimum, the liability o-f accidental displacement of the several elements.

In the drawing; forming a part of this application Y Figure 1 is a tool.

Figure 2 is a detail longitudinal section. Figure 3 is a transverse enlarged section. taken substantially on the line 3-3 of Figure 2, and

Figure side elevation of my improved Y 4- is an enlarged detail view of the polishing head detachahly associa-ted with the revolving shank.

`New having particular reference to the drawing, my invention consists of a. tubular handle 5, of predetermined length open at its opposite ends, one end thereof being equipped with a removable plug 6, while the opposite end thereof is slightly flanged inwardly to provide a. circular abutment 7. The tool further consists of a polishing head receiving stem or shank 8, preferably formedofa pair of twisted wires so that said stem or shank will be of spiral formation. Upon the inner end of the stem is a circular plate 9, freely movable within the tubular handle 5, and upon the innerface of which is formed or disposed a rounded metallic head 10. Upon the opposite end of the stem 8 there is arranged somewhat elongated sleeve 11, the outer end of which is formed or provided with a tapered pin 12. For frictional engagement upon this tapered pin 12 there is provided a polishing head that consistsy of a Vi'netallie sleeve 13, the inner end of the bore thereof being-tapered for frictionally receiving the tapered pin 12 of the sleeve 11.y The bore at the opposite end ofr this sleeve 13 is of enlarged diameter to provide a pocket 14, which vpocket communicates with theftapered end of the sleeve bore through a restricted vopening 15.V This pocket '1e is 'provided' for receivingthreads or strips of chamois or otherlpolishving material, a` plurality of which is prefer# ably provided, the-preferred manner of disposing t-he same within lthe pocket being t0 provide a length of thin wire that may be bent intermediate its ends around the threads or strips of c han'ioisbetween the ends thereof, after which the wire is passed through the sleeve 13 and then pulled so as to force the material into. the pocket, theflength of the threads or strips of material being such that when turned over andspulled into the pocket,

the bightportions will be against the bottom f of the pocket, while the ends thereof will project therefrom as clearly disclosed in Figures 1, 2, and t to provide a polishing nose 16.

Arranged within the tubular handle 5 is an elongated expansible coil spring 17, that bears against the plug 6, at one end, and within the opposite end of which is arranged a pin 18 formed at its lower end with a metal- 'c ball shaped head 19 for engaging the head 10, upon the inner end of, the spiral stem or shank 8 previously described. It will be vthus seen that the polishing'head carrying stein 8 will be normally projected from the tubular handle 5 by reason of the coil spring i 1T. However, by placing the polishing nose 16 of the tool head within a watch jewel setting and then forcing theV handle 5 downwardly, such an action will cause the moreF ment of the handle over the stem 8 and the rotation of the stem and consequently a rotation of the polishing head. is pressure is released from the handle 5, the spring 17 will serve to project the stein therefrom and during such projection a reversal of rotation of the lstem and the polishing head will be brought about. The tool may be used either before the jewel is set or after the jewel has been removed. The'tool may furthermore l .i used to polish the jewel while the same is se cured in the setting or where the jewel is held in any suitable vise or other supporting means independent of the setting of the watch case.

1t will thus be seen that I have provided a highly novel, eliiciently operating watch jewel setting polisher that is well adapted for all of the purposes heretofore designated, and even though I have herein shown and de# scribed the invention as consisting of certain details of structure, it is nevertheless to be understood that Isome changes may be made therein without affeeting'th'e spirit vand scop'e of the appended claims.

Having thus vdescribed my invention, Vwhat I claim as new is i 1,. In a polisher of the class described, a stem, a handle on one end of the stem, a sleeve secured on the other end of the stem, atapered pin formed on the outer end of the sleeve, an 'additioinal sleeve, the inner end of the bore thereofbeing taperedv for fric tionally receiving the vtapered pin, and a polishing'member carried'by the outer end of the last mentioned sleeve.

'In appolisher of the class described, a stem, aliandl'e on one end 'of the stem, a sleeve secured on the' otherv end of the stem, a tapered pin formed on the outer end of the sleeve, an additional sleeve, the inner end of the bore thereof being tapered for lrictionally receiving the taperedpin, the outer end of the bore of the last mentioned sleeve being Less-Levi enlarged to provide a pocket, and a polishing member secured within the pocket, the outer end of the polishing member projecting beyond the outer end ot said sleeve.

3. In a tool of the class described, a spiral stem, a polishing head carried by the lower end of said stem,a tubular handle, the lower end of the handle being formed with an in-V wardly directed flange for cooperation with the spiral stem to elect the rotation vof the stem when the tubular handle is moved downwardly on the stem," av normally expansible coil spring arranged in the tubular handle, the upper end of said spring engaging the closed upper end ofL the tubular handle, 'a pin secured in the lower end of said' eXpan-V ible coil spring, a ball shaped head formed on the'lower end of said pin, a plate carriedi by the upper end of the stem and operable within the tubular handle,l aball 'shaped head arranged on the upper face of the plate for engagement with the aforesaid ball shaped head, said expansibl'e 'coil spring normally urging the tubular handle to its uppermost position with respect to the stem. l

In testimony whereof I affix my signature.
